If you begin with a recognized "pure" mixture the sugar and water, then what you propose is fine, to an extent, if you are just after separating the 2 ingredients.
Crystallisation is a purification technique for extract a solid native solution; it will allow you to different pure solute from the solvent. The continuing to be solution would still contain a tiny amount of liquified material, and hopefully every one of your impurities.

If you want to isolate pure solvent indigenous the solution, you would need to use distillation. After ~ collecting the distillate, you would certainly be left with a gummy residue of semi-decomposed sugar (and your impurities).
Sugar is hygroscopic, and also starts decomposing at simply over 180°C (~365°F). The problem that friend would have actually with your proposed an approach is the in bespeak to remove the final remnants that the water, you will need to warmth well over the boiling allude of water. Google "making caramel" if you can"t think the what will happen. Even a very small amount that decomposition of your sugar will median you are left v an impure solid. Ago to square one. The factor that you can simply boil the water turn off salt is the it is far much more stable and can be heated safely come much higher temperatures.

So, there are a couple of ways to different these two ingredients, depending on your finish goals:To collect simply solute (sugar): warmth over really low warmth to evaporate as lot water as feasible to provide yourself a saturated solution. Climate crystallise sugar and also filter (in the rap you"d wash through a perfect solvent and dry under vacuum)To collect simply the solvent (water): distill end moderate warm to collection water. To collection as much as possible, the warmth used to cook off the solvent demands to be progressively increased, especially as you technique the final portion.To collect both solute (sugar) and solvent (water): girlfriend would remove solid first, climate distil solvent. Uneven you are beginning with a saturated solution, girlfriend would must do a partial distillation to remove some solvent, climate crystallise your sugar, then finish the distillation. You"d still it is in left through a horrible brown gummy residue.
Sounds choose a great home project, though. Simply be certain to have done some perfect research to allow you to make use of your materials if it doesn"t rather go to setup :-)
